Product Introduction
Core Properties & Advantages for Eyeglasses
Low Elastic Modulus (~148 GPa): Significantly more flexible than pure Ti or Ti-6Al-4V (Gr5).
Excellent Shape Memory: Bends without permanent deformation. The temple arms can be twisted or bent and will snap back to original shape, providing "unbreakable" comfort.
High Yield Strength: Resists permanent set under stress.
Superior Strength & Lightweight
High Strength-to-Weight Ratio: Stronger than pure titanium while maintaining the same low weight.
Tensile Strength (Solution Treated): ≥ 640 MPa
Allows for Slimmer Designs: Enables thin, delicate temple arms and frames that are still strong.
Excellent Cold Formability
Exceptional ductility in the solution-treated state.
Easy to bend, shape, and process into intricate frame designs without cracking.
Ideal for manufacturing complex, modern, and minimalist eyewear styles.
Outstanding Biocompatibility & Corrosion Resistance
Hypoallergenic: Nickel-free, making it 100% safe for sensitive skin.
Excellent Corrosion Resistance: Forms a stable, protective oxide layer, resistant to perspiration and cosmetics.
Long-Lasting Finish: Maintains its luster and prevents tarnishing.
Typical Specifications for Eyewear
Diameter Range: 0.8 mm – 6.0 mm
Forms: Coiled wire, spooled wire, cut straight wire
Surface Finish: Bright polished, pickled (acid-cleaned)
Temper/Condition:
M (Annealed/Solution Treated): Soft, highly formable for bending.
Y (Cold Worked/Aged): High strength and elasticity for finished parts.
Primary Applications in Eyeglasses
- Elastic Temple Arms: The most common use. Provides the perfect "spring hinge" feel and long-term comfort.
- Rim Frames & Frontals: For ultra-lightweight, thin, and flexible full-rim or half-rim designs.
- Bridge Components: For flexible, adjustable nose bridges.
- High-End & Sport Frames: Preferred for designer, luxury, and sports eyewear where maximum comfort, durability, and flexibility are required.
